Matter and Energy in the Ecosystem

1. How do bears most likely obtain energy in an ecosystem?

Sun ---> Berry ---> Rabbit ---> Bear

• form the sun

• the bear consume rabbit

• the bear produce energy from the sun

2. How do limiting factors affect the amount of organisms in an ecosystem?

• Living components of an Ecosystem.

• Controls a process, such as organism growth or species population, size, or distribution.

• Period when a plant is not actively growing, but is still alive.

3. Outline the Carbon Cycle

• The circulation and reutilization of carbon atoms, especially via the processes of photosynthesis, respiration and decomposition.

• 
• cycle of processes by which water circulates between the earth's oceans, atmosphere, and land

4. Define decomposers?

• An organism that obtains energy by feeding on other organisms.

• An organism that can make its own food.

• An organism that breaks down wastes and dead organisms.

• bacteria, fungi, some insects, and snails

4. Define producers?

• An organism that obtains energy by feeding on other organisms.

• An organism that can make its own food.

• Animals that feed on dead, sick or injured prey.

• PLANTS...

4. Define consumers?

• herbivores, omnivores, and carnivores

• An organism that breaks down wastes and dead organisms.

• An organism that can make its own food.

• An organism that obtains energy by feeding on other organisms.

5. In a deciduous forest biome, trees enter a form of hibernation. What is the form called?

• Period when a plant is not actively growing, but is still alive.

• The process whereby seeds or spores sprout and begin to grow.

• they become dormant.

• The movement of plant parts toward or away from a stimulus

6. List examples of external stimuli, and how they impact plants in an ecosystem.

• phototropism: response to sunlight

• thigmotropism: response to touch

• hydrotropism: response to water

• geotropism: gravity

7. Explain how biomes with heavy precipitation are different from biomes with low precipitation.

• heavy precipitation are wet with high in soil nutrients; while low precipitation are hot and dry

• Enough rain for trees to grow. They lose their leaves in the fall.

• Made up of rivers, ponds, lakes and streams and my water does not have much salt

8. List the parts of a flower, and provide the role each one plays in plant reproduction.

• filament supports the anther

• stamen is female

• pistil contains the stigma, ovules, and ovaries
